no longer needed now that the sparse runtime support library

This patch is the first in a series of patches fixing markdown links and references inside the mlir documentation. I chose to split it in a few reviews to be able to iterate quicker and to ease review.
This patch addresses all broken references to other markdown files and sections inside the Dialects folder.
One change that was also done was to insert '/' between the markdown files and section:
Example:
Builtin.md#integertype
was changed to:
Builtin.md/#integertype
After compilation, hugo then translates the later to jump directly to the integer type section, but not the former. Not inserting the slash would simply jump to just the Builtin page, instead of the integertype section. I therefore changed occurrences of the former version to the later as well.

This exposes the iterations and top-down processing as flags, and also
allows controlling whether region simplification is desirable for a client.
This allows deleting some duplicated entrypoints to
applyPatternsAndFoldGreedily.
This also deletes the Constant Preprocessing pass, which isn't worth it
on balance.
All defaults are all kept the same, so no one should see a behavior change.

Steps for normalizing dynamic memrefs for tiled layout map
1. Check if original map is tiled layout. Only tiled layout is supported.
2. Create normalized memrefType. Dimensions that include dynamic dimensions
in the map output will be dynamic dimensions.
3. Create new maps to calculate each dimension size of new memref.
In tiled layout, the dimension size can be calculated by replacing
"floordiv <tile size>" with "ceildiv <tile size>" and
"mod <tile size>" with "<tile size>".
4. Create AffineApplyOp to apply the new maps. The output of AffineApplyOp is
dynamicSizes for new AllocOp.
5. Add the new dynamic sizes in new AllocOp.
This patch also set MemRefsNormalizable trant in CastOp and DimOp since
they used with dynamic memrefs.

This adds the ability to specify a location when creating BlockArguments.
Notably Value::getLoc() will return this correctly, which makes diagnostics
more precise (e.g. the example in test-legalize-type-conversion.mlir).
This is currently optional to avoid breaking any existing code - if
absent, the BlockArgument defaults to using the location of its enclosing
operation (preserving existing behavior).
The bulk of this change is plumbing location tracking through the parser
and printer to make sure it can round trip (in -mlir-print-debuginfo
mode). This is complete for generic operations, but requires manual
adoption for custom ops.
I added support for function-like ops to round trip their argument
locations - they print correctly, but when parsing the locations are
dropped on the floor. I intend to fix this, but it will require more
invasive plumbing through "function_like_impl" stuff so I think it
best to split it out to its own patch.
This is a reapply of the patch here: https://reviews.llvm.org/D102567
with an additional change: we now never defer block argument locations,
guaranteeing that we can round trip correctly.
This isn't required in all cases, but allows us to hill climb here and
works around unrelated bugs like https://bugs.llvm.org/show_bug.cgi?id=50451

All lines after the first are currently indented by one char further to the left than the first line. This leads to the first character of each sentence being cut from the resulting Markdown file after compilation. The text also contains 3 references to sections of other markdown files. One was missing the file, while the other two had outdated files, leading to 404 errors in the documentation.

This revision completes the "dimension ordering" feature
of sparse tensor types that enables the programmer to
define a preferred order on dimension access (other than
the default left-to-right order). This enables e.g. selection
of column-major over row-major storage for sparse matrices,
but generalized to any rank, as in:
dimOrdering = affine_map<(i,j,k,l,m,n,o,p) -> (p,o,j,k,i,l,m,n)>

This pattern inlines operands to a linalg.generic operation that use a constant
index and hence are loop-invariant scalars. This reduces the number of
linalg.generic operands and unlocks some canonicalizations that rely on seeing
an explicit tensor.extract.

The current implementation has several key limitations and weirdness, e.g local reproducers don't support dynamic pass pipelines, error messages don't include the passes that failed, etc. This revision refactors the implementation to support more use cases, and also be much cleaner.
The main change in this revision, aside from moving the implementation out of Pass.cpp and into its own file, is the addition of a crash recovery pass instrumentation. For local reproducers, this instrumentation handles setting up the recovery context before executing each pass. For global reproducers, the instrumentation is used to provide a more detailed error message, containing information about which passes are running and on which operations.
Example of new message:
```
error: Failures have been detected while processing an MLIR pass pipeline
note: Pipeline failed while executing [`TestCrashRecoveryPass` on 'module' operation: @foo]: reproducer generated at `crash-recovery.mlir.tmp`
```

Original interfaces are not safe to be called during dialect conversion.
This is because some ops (e.g. `dynamic_reshape(input, target_shape)`)
depend on the values of their operands to calculate the output shape.
However the operands may be out of reach during dialect conversion (e.g.
converting from tensor world to buffer world). This patch provides a new
kind of interface which accpets user-provided operands to solve this
problem.

"[mlir] Speed up Lexer::getEncodedSourceLocation"
This reverts commit 3043be9d2d and commit
861d69a525.
This change resulted in printing textual MLIR that can't be parsed; see
review thread https://reviews.llvm.org/D102567 for details.
At present, a lot of code contains main function bodies like "return failed(mlir::MlirOptMain(...);". This is unfortunate for two reasons: a) it uses ADL, which is maybe not what the free "failed" function was designed for; and b) it is a bit awkward to read, requring the reader to both understand the boolean nature of the value and the semantics of main's return value. (And it's also not portable, since 1 is not a portable success value.)
The replacement code, `return mlir::AsMainReturnCode(mlir::MlirOptMain(...))` is a bit more self-explanatory.
The change applies the new function to a few internal uses of MlirOptMain, too.

This is a hook that allows for providing custom initialization of the pattern, e.g. if it has bounded recursion, setting the debug name, etc., without needing to define a custom constructor. A non-virtual hook was chosen to avoid polluting the vtable with code that we really just want to be inlined when constructing the pattern. The alternative to this would be to just define a constructor for each pattern, this unfortunately creates a lot of otherwise unnecessary boiler plate for a lot of patterns and a hook provides a much simpler/cleaner interface for the very common case.

The FIRRTL dialect in CIRCT uses inherently signful types, and APSInt
is the best way to model that. Add a couple of helpers that make it
easier to work with an IntegerAttr that carries a sign.
This follows the example of getZExt() and getSExt() which assert when
the underlying type of the attribute is unexpected. In this case
we assert fail when the underlying type of the attribute is signless.
This is strictly additive, so it is NFC. It is tested in the CIRCT
repo.

This change makes the conversion of an mlir::OpState to bool `explicit`. Idiomatic boolean uses continue to work as before, but questionable implicit uses (e.g. accumulating over a range of OpStates to count "true" states) become ill-formed. This makes the class interface a lilttle less error-prone.
I tested this change on our internal (fairly large) codebase, and only one fix was needed, which was ultimately an improvement of the affected code.
